Against poststructuralism

I thought these reflections by Mariano Zukerfeld on pg 4 of his Knowledge in the Age of Digital Capitalism were absolutely spot on. It would unfair to present this as a characteristic of poststructuralism as such, but there can be a dogmatism to poststructuralist thinkers which is all the more frustrating for their own obliviousness to it:

On the one hand, much of its indisputable publishing success has been based on concepts that, even though they seem attractive initially, are ultimately beautiful but of little use. On the other hand, many of these critical philosophical initiatives, when they engage with discussions about the capitalist economy, adopt concepts from orthodox economics in a completely naturalised and acritical way. Thus, they ascend to their concepts upon the scaffolding provided by the dominant ideology. More generally, I do not share these approaches’ rejection of the categories of totality, contradiction, negativity, and I believe that much of their blithe positivity makes them functional to the dominant ideology of informational capitalism. Finally, this tradition brandishes the banners of difference, otherness, multiplicity. However, in practice it is no more adept at dialogue with difference (in other words with those viewpoints that do not echo its mantras) than any other dogmatism. This intolerance in the face of plurality, debate, and constitutive contradictions, that for Marxism, scientism, or any religion can be explained (disagreeably but with coherence) by the belief that there is one truth, which they are in possession of, is completely unsustainable when observed in these ‘philosophies of difference’ .
